Commemorated June 1 in the Orthodox Christian Menaion

From the Prologue

These all suffered in Rome in the time of Marcus Aurelius and the Eparch
Rusticus. When Rusticus asked: 'Do you think that, if you die for Christ, you
will receive a reward in heaven?', Justin replied: 'We do not think it; we know!'
They were all then beheaded, in 163, and went to the Kingdom of Christ our
God.
